Re: T510 combo mic/audio port usage?

Now, the question I've been waiting to ask. I sometimes need to record output coming out of the computer. With my T41p, since it has 2 separate miniplug ports (1 for out, 1 for in), I was able to use that Y-cable I told you about to plug into the T41p out. Then, one fork would go to my headphones so I can listen to what I'm recording. The other fork would connect to a male-to-male miniplug wire which would connect back into the T41p in. This way I can record stuff that I play on my computer.

Now with the T410s, I would obviously have to do it a little differently. I would use that iPhone Y-cable and plug into the T410s miniplug port. Then, the out part of the iPhone cable would connect to my Y-cable. One of the forks on my Y-cable would go to my headphones. The other fork on my Y-cable would connect to a male-to-male miniplug wire which would loop back and connect to the in part of the iPhone cable.

This would work, right? In effect, I'm assuming that attaching the iPhone cable on the T410s would be the equivalent of my T41p setup (since it has 1 in and 1 out, stock), except it just doesn't look tidy like the T41p.

Re: T510 combo mic/audio port usage?

I designed this adapter for use with my customers and the ThinkPads we sell (I'm a Lenovo Reseller). It's a 4 pole male splitter to stereo female (headphone) connector and mono female (microphone) connector. My customers NEED to use standard mics, and this works perfectly.

So the MIC is on the most far outer end. Usual Plugs have their body there. It makes the wiring rather difficult. Because shielded cable outer shield can't go on that usual position but shall go on the 3rd ring from tip.

This kind of silly cabling is also used from iPhone. The Nokia pinning is different and has the more logical pinning left - right - Mic - Gnd. So you cant use Nokia or Video camcorder adapters on the Lenovo or iPhone 4-pin audio jack.

For a pure headset that doesn't matter at all, as the ground on the 3-pin plug covers both MIC and GND positions.
